I worked at a government agency in the early 90s. We had drafts people. One of the big issues was computer cad took longer and the drawings looked worse. Printing blueprint size was difficult. They drawing were on some wierd “vellum” like semi transparent material so they could make copies in the blueprint room which always smelled like ammonia. Of course once you had edits the manual drawing speed advantage went away and plotting/printing tech soon caught up. One of the drafts people had a power eraser that would sound a round white eraser tip like a drill.
